CORPORATION OF VERMONT.

CENTRIFUGAL SEPARATOR.

SPECIFICATION forming part of Letters Patent N 0. 712,310, dated October 28, 1902.

Application filed May 29, 1902. Serial No. 109,456. (No model.)

To all whom it may concern: v

Be it known that I, PERLEY L. KIMBALL, a citizen of the United States of America, re

siding at Bellows Falls, in the county of Windham and State of Vermont, have invented certain new and useful Improvements in Centrifugal Separators, of which the following is a specification.

The object of my invention is to provide a device of the class'specified having features of novelty and advantage.

Figure 1 is a view in side elevation of a separator-bowl, partly broken away to show construction. Fig. 2 is a sectional plan view on the line x x of Fig. 1. tional perspective View of the interior of the bowl. Fig. 4 is a sectional plan view on the line 00 m of Fig. 1.

In the drawings, A denotes the separatorbowl. y

B B denote the escape-passages for the skim-milk through the bottom of the separator-bowl.

C denotes an annular projection or ring on the interior wall of the bowl at or near the bottom thereof.

D D are vertical mortises through this ring, one side of the mortises preferably beingformed by the interior wall of the bowl. I

E E denote lateral openings or outlets with which the verticatmortises D D communicate. These lateral openings preferably are flared, so that they can be easily cleaned. Extending upward from this annular projection or ring are tapering webs F F, which act as guides to direct the liner G to its proper position. The liner is adapted to fit inside of the annular projection or ring and is held above the bottom of the bowl bya spacing device, as the boss K. -As shown in the drawings this boss is secured to the bottom of the liner; but it may be equally well secured to the bottom of the bowl, On the bottom of the liner there are also located wings M N.

Asthe blue milk is separated from the cream it moves outwardly to the wall of the bowl and then down, passing through the mortises and the outlets into the space between the bottom of the liner and the floor Fig. 3 is a sec of the-bowl. The wings on the bottom of the liner keep this blue milk moving and cause it to flow out through the escape-passages B B. l leretofore tubes have been secured to the floor of the bowl, extending from its walls over the skim-milk-escape tubes; but it has been found that uncleanly persons would not properly cleanse these tubes and in some extreme cases even allow them to become clogged. To overcome these objections, I have devised the bowl herein shown and described, which performs the work required of it with, extreme thoroughness and is readily cleaned and kept in a sweetand pure condition.

I claim as my invention- 1. In combination; a separator-bowl; a projection from the interior wall of the bowl and located near the floor thereof; the liner; and a spacing device between the liner and the floor of the bowl, substantially as described and for the purposes set forth.

2. In combination; a separator-bowl; the

annular projection from the interior wall of and the floor of the bowl, substantially as described.

4:. In combination; a separator-bowl; an an nular projection from the interior wall'of the bowl and located near the floor thereof; slantfaced guides appurtenant to said projections; and a liner carrying a supporting-boss underneath, substantially as described and for the purposes set forth.

5. In combination; a separator-bowl having escape-conduits for the blue milk through its floor; a liner carrying downwardly-projecting wings on its lower end; an annular projection from the interior wall of the bowl erally by flare-mouthed openings with the having vertical mortises communicating laterally with the space between the liner and the floor of the bowl, substantially as described.

6. In combination; a separator-bowl having escape-conduits for the blue milk through its floor; a liner carrying downwardly-projecting wings on its lower end; an annular projection from the interior wall of the bowl having vertical mortises communicating latspace between the bottom of the liner and the floor of the bowl, substantially as described and for the purposes set forth.

In testimony whereof I affix my signature in presence of two witnesses.
